Custom Fields to Meta Tags lets you leverage WordPress custom fields to generate <code><meta></code> tags in your site’s <code><head></code> section.
Simply add a custom field to your post or page with a key that starts with cfmt, and the plugin will automatically turn it into a meta tag.
Example: 
– Custom field key: <code>cfmtdescription</code> 
– Custom field value: <code>Description of the post/page</code> 
– Output in <code><head></code>:
 
<h3>Key Features</h3>
<ul>
<li>Lightweight, zero-configuration – just activate and use.</li>
<li>Prefix-based system (<code>cfmt</code>) to avoid conflicts.</li>
<li>Works with posts, pages, and custom post types.</li>
<li>Useful for creating:
<ul>
<li>Meta descriptions</li>
<li>Author or copyright tags</li>
<li>Custom SEO tags</li>
</ul>
</li>
</ul>
<h3>Why use this plugin?</h3>
Most SEO plugins are heavy and packed with features you may not need. If you only want to generate custom meta tags directly from WordPress custom fields, this plugin is the simplest solution.
No settings page, no bloat — just pure functionality.

Custom Fields to Meta Tags

Use WordPress custom fields (with a prefix) to automatically output SEO meta tags (like description) in the  section of your posts and pages.

WPGurus

This tiny plugin allows you to use spintax like <code>{phrase 1|phrase 2|phrase 3}</code> in your posts, pages and theme files. Just enclose the content that you want to be processed in the shortcode [wpts_spin][/wpts_spin] and a unique copy will be generated on each page load. Alternatively, you can pass the spintax string to the function <code>wpts_spin()</code> and echo the returned value.
The plugin can help you avoid duplicate content penalties. For instance if you have a sizable block of text that needs to appear throughout the website then you can write spintax for it and use the above-mentioned shortcode or template tag to generate unique copies.
Nested spintax like <code>{phrase 1|phrase 2|{sub-phrase 1|sub-phrase 2|sub-phrase 3}}</code> is also supported by the plugin.
Example 1:
Shortcode:
<pre><code>[wpts_spin]{phrase 1|phrase 2|phrase 3}[/wpts_spin]
</code></pre>
Function:
<pre><code><?php wpts_spin('{phrase 1|phrase 2|phrase 3}'); ?>
</code></pre>
Sample Output:
<ul>
<li>phrase 1</li>
<li>phrase 2</li>
<li>phrase 3</li>
</ul>
Example 2 (Nested Spintax):
Shortcode:
<pre><code>[wpts_spin]{phrase 1|phrase 2|{sub-phrase 1|sub-phrase 2|sub-phrase 3}}[/wpts_spin]
</code></pre>
Function:
<pre><code><?php wpts_spin( '{phrase 1|phrase 2|{sub-phrase 1|sub-phrase 2|sub-phrase 3}}' ); ?>
</code></pre>
Sample Output:
<ul>
<li>phrase 1</li>
<li>sub-phrase 2</li>
</ul>
Example 3 (Caching):
Shortcode:
<pre><code>[wpts_spin cache="604800"]{phrase 1|phrase 2|phrase 3}[/wpts_spin]
</code></pre>
Function:
<pre><code><?php wpts_spin( '{phrase 1|phrase 2|phrase 3}', array( 'cache' => '604800' ) ); ?>
</code></pre>
Sample Output:
Same as Example 1 but the output will be cached for a week (604800 seconds).
